Description

Technical Field

[0001] Embodiments of the present invention relate to the field of digital twins, and in particular to a twin mapping method that integrates a power mode and a deep learning model. Background Art

[0002] Geographic Information System (GIS) is the digitization of physical geographic systems. It maps physical geographic systems into computers in the form of points, lines, surfaces, and volumes, making them information geographic systems. With the development of sensor networks, the Internet of Things, Building Information Modeling (BIM), modern communications and other technologies, GIS has developed into digital twins. Digital twins were first used by NASA in the Apollo program in 1969 to build twins of spacecraft. In 2003, the concept of digital twins was formally proposed by Michael Grieves of the University of Michigan. It was initially named the "Information Mirroring Model" and later evolved into the term "digital twin". To date, many different definitions of digital twins have been born, but in essence, they can be understood as "3D clones" or "twins" of physical space, which are twins of static physical space.

[0003] However, the geographical process of physical space changes with time, scene, granularity, etc. For example, the self-purification process of pollutants exchanged between island reef lagoons and offshore waters will change with time, ocean currents, monsoons, etc. The self-purification process of water quality in lagoons has the characteristics of dynamic physical processes. How to twin map and visualize the dynamic geographical process of physical space is an urgent problem to be solved. Summary of the invention

[0004] An embodiment of the present invention provides a twin mapping method that integrates dynamic patterns and deep learning models, which can quickly calculate spatial distribution field data at different times in the future based on real-time monitoring data, and realize twin mapping and visualization of the entire life cycle of geographic dynamic processes.

[0005] In a first aspect, an embodiment of the present invention provides a twin mapping method integrating a power mode and a deep learning model, including:

[0006] According to the twin mapping scenario to be simulated, the environmental factor data of the target area is collected in real time;

[0007] Using the physical dynamic model, numerically simulate the twin mapping scene of the target area, and use the environmental factor data to correct the numerical simulation results to obtain the spatial distribution data of the environmental factor;

[0008] The spatial distribution data of the environmental factors are used as samples to train a lightweight deep learning model, wherein the trained model uses the historical spatial distribution data of the environmental factors as input and uses the future spatial distribution data of the environmental factors as output;

[0009] The environmental factor data collected in real time is input into the trained model, and the future environmental factor data of the target area is predicted in real time and displayed visually.

[0010] In a second aspect, an embodiment of the present invention provides an electronic device, the electronic device comprising:

[0011] one or more processors;

[0012] a memory for storing one or more programs,

[0013] When the one or more programs are executed by the one or more processors, the one or more processors implement the twin mapping method of the fusion power mode and the deep learning model described in any embodiment.

[0014] In a third aspect, an embodiment of the present invention further provides a computer-readable storage medium on which a computer program is stored, which, when executed by a processor, implements the twin mapping method of the fusion power mode and the deep learning model described in any embodiment.

[0015] The embodiment of the present invention provides a twin mapping method that integrates physical dynamic mode and deep learning model. It uses sensor real-time monitoring technology, combines traditional physical dynamic mode and lightweight deep learning model, and can quickly calculate the spatial distribution field data at different times in the future according to real-time monitoring data, so as to realize the twin mapping and visualization of the whole life cycle of geodynamic process. The present invention overcomes the shortcomings of traditional high-precision hydrodynamic mode, such as large amount of calculation, slow calculation speed, and dependence on large supercomputers for computing power. It can quickly calculate the spatial distribution of pollutant concentration field and realize the rapid twin mapping and visualization of geographic process. However, the sensor monitoring data can only represent the "instantaneous" state of water environment elements at a certain monitoring point, and it is difficult to reflect the large-scale spatial distribution changes of geodynamic process. The present invention can quickly calculate the spatial distribution field data of island, reef and lagoon water environment at different times in the future according to real-time monitoring data and using lightweight deep learning model.

[0023] Figure 1 This is a flow chart of a twin mapping method that integrates a power mode and a deep learning model provided by an embodiment of the present invention. The method is applicable to the case of simulating a twin mapping scenario with a dynamic physical process and is executed by an electronic device. Figure 1 As shown, the method specifically includes:

[0024] S110. Collect environmental factor data of the target area in real time according to the geodynamic process of the twin mapping scene.

[0025] The twin mapping scene here refers to the geodynamic scene to be simulated, and different twin mapping scenes require different environmental data. This embodiment first determines the actual environmental data to be collected according to the geodynamic process of the specific scene as the data source of the entire method.

[0026] In a specific implementation, taking the twin mapping scenario of the self-purification of pollutants in island reef lagoons as an example, the corresponding target area is the lagoon, and the geodynamic process in the scenario is the dynamic process of water exchange between the lagoon and the open sea. First, according to the dynamic process of water exchange between the lagoon and the open sea in the self-purification of pollutants in island reef lagoons, relevant sensors are deployed near the sewage outlets of island reef lagoons. Then, the water environment factor data of the lagoon is collected in real time through each sensor, including pollutant concentration (such as nitrogen concentration, phosphorus concentration), seawater temperature, seawater salinity, ocean current field and other water environment element data.

[0027] S120. Use the physical dynamic model to perform numerical simulation on the twin mapping scene of the target area, and use the environmental factor data to correct the numerical simulation results to obtain the spatial distribution data of the environmental factors.

[0028] Still taking the self-purification scenario of island reef lagoon pollutants as an example, this step uses mature physical dynamic models, such as FVCOM (Finite Volume Community Ocean Model, a high-precision hydrodynamic exchange model), to numerically simulate the lagoon water exchange process, and correct its parameters in combination with real-time monitoring data to ensure that the simulation results are accurate and reliable. This process may include the following steps:

[0029] Step 1: Determine the model parameterization scheme based on the opening and closing of the island and reef lagoon, terrain and wind field effects. Optionally, set the large-scale sea area where the island and reef lagoon is located as the initial area to determine the parameterization scheme for the model operation, which includes the simulation time resolution, spatial grid resolution, simulation time range, lagoon bottom type, lagoon mixing rate (mixing rate of temperature and salinity inside the lake), etc.

[0030] Step 2: Based on the historical observation data and field survey data of island and reef lagoons, the physical dynamic model is used to numerically simulate the lagoon water exchange process. Optionally, four types of external forcing conditions, such as wind, open boundary, river, and meteorological conditions, are first used to run the large-scale coarse-resolution FVCOM hydrodynamic model to simulate the large-scale field data of water environmental factors, namely nitrogen concentration, phosphorus concentration, seawater temperature, seawater salinity, current field and other large-scale field data. Then, according to the shoreline, topography and geomorphic data of the target island and reef lagoon, the island and reef lagoon area is refined and nested in the network to construct the FVCOM high-precision hydrodynamic model of the island and reef lagoon area. Thirdly, the output results of the large-scale coarse-resolution FVCOM hydrodynamic model are used as open boundary conditions for nitrogen concentration, phosphorus concentration, seawater temperature, seawater salinity, and ocean current field. Combined with the observation data of temperature, salinity, ocean currents, etc. in the historical period of island and reef lagoons and the survey data of ocean dynamic environment such as wind, waves, and currents, the FVCOM high-precision hydrodynamic model of the island and reef lagoon area is called to simulate and generate water environment data of the lagoon in the historical period.

[0031] Step three, use the environmental factor data collected in real time to correct the parameters of the numerical simulation results to ensure that the simulation results are accurate and reliable, and finally obtain the spatial distribution data of nitrogen concentration, phosphorus concentration, seawater temperature, seawater salinity, and ocean current field at different times in the lagoon. Optionally, the environmental factor data collected in real time can be interpolated and preprocessed to convert it into data in the same format as the numerical simulation results; then use the data assimilation method to merge the converted data with the numerical simulation results to obtain the spatial distribution data of nitrogen concentration, phosphorus concentration, seawater temperature, seawater salinity, and ocean current field at different times in the lagoon, wherein the data assimilation method includes at least one of the variational method, Kalman filtering, or particle filtering, and the specific process of each data assimilation is prior art and will not be repeated here.

[0032] Since the small area of ​​the island reef lagoon is not completely closed, but is affected by the external ocean temperature field, salinity field, tide and other conditions, long-term data observation is required to obtain these conditions. When it comes to a specific island reef, it is usually difficult to obtain the required data. Therefore, this embodiment constructs a larger-scale coarse-resolution dynamic model of the sea area where an island reef is located in the above-mentioned manner. Due to its low resolution requirements and large simulation range, it is relatively easy to find the basic data required for model construction and provide the target island reef lagoon with the required basic boundary condition data. If a designated small area has been observed for a long time and all kinds of data are complete, there is no need to build a large-scale model, and high-precision modeling can be directly performed on the small area. This embodiment does not make specific restrictions.

[0033] S130. Using the spatial distribution data of the environmental factors as samples, a lightweight deep learning model is trained. The trained model uses the historical spatial distribution data of the environmental factors as input and the future spatial distribution data of the environmental factors as output.

[0034] Physical dynamic mode technology has disadvantages such as large amount of calculation, slow operation speed, and heavy reliance on supercomputers. Simply using this technology for twin mapping of geographic processes cannot meet the real-time requirements. In order to make up for this defect, this embodiment introduces a deep learning model with extremely high computational efficiency into the twin mapping of geographic processes, inputs a large amount of time-series geographic process data into the deep learning model for training, obtains the evolution law of geographic processes from the data, and realizes rapid simulation of geographic processes, thereby meeting the needs of real-time mapping of geographic processes. Optionally, a convolution-long short-term memory neural network model (ConvLSTM) can be used as the lightweight deep learning model, and the spatial distribution data of environmental factors at multiple consecutive moments before and after any moment are extracted as samples; the spatial distribution data of environmental factors at multiple consecutive moments before the moment are input into the lightweight deep learning model for training, so that the model output continuously approaches the spatial distribution data of environmental factors at multiple consecutive moments after the moment.

[0035] Still taking the self-purification scenario of island reef lagoon pollutants as an example, first, based on the simulation data of high-precision hydrodynamic exchange patterns obtained in S120 (spatial distribution data of seawater temperature, salinity, current field, nitrogen concentration, phosphorus concentration, etc. at different times in the lagoon), training samples are constructed and divided into training set, validation set and test set in a ratio of 7:2:1. The ConvLSTM model is a supervised learning model, which needs to determine the input features and output labels. The determination method is to select T 1 ,T 2 ,…,T n , that is, the field data at n moments is used as the input feature, and T n+1 ,T n+2 ,…,T n+k , that is, the field data at k moments is used as the output label. This method is applied to the training set, validation set, and test set to divide the features and labels. Then, the ConvLSTM model is trained using the above data set, and the deep learning model parameters are gradually optimized through the gradient descent method to minimize the training set error. Finally, the validation set and test set are used to evaluate the model effect. If the result does not meet the accuracy requirements, the hyperparameters need to be changed and the model needs to be retrained until the model accuracy meets the requirements.

[0036] Furthermore, one can use Figure 2The ConvLSTM model architecture shown in Figure 1. The model is divided into two layers, and deeper layers can better extract the feature information of the data. The model input data X(t, input_channels, height, weight) and output data Y(t, output_channels, height, weight) are both 4-dimensional tensors, where the first parameter t represents the time step, the second parameter represents the number of channels of the input and output grid data, and each channel represents a variable, such as temperature, salinity, etc. The third and fourth parameters represent the height and width of the input grid data.

[0037] S140, inputting the environmental factor data collected in real time into the trained model, dynamically predicting the future environmental factor data of the target area in real time and displaying them visually.

[0038] In the example of the self-purification process of pollutants exchanged between island reef lagoons and offshore water quality, the water environment element data of island reef lagoons monitored in real time can be used as input, and a lightweight deep learning model can be called to simulate and calculate the spatial distribution data of the lagoon water environment at different times in the future, such as the spatial distribution data of the water environment in the next 1 hour, 2 hours, 3 hours, ..., 6 hours (grid field data), and store them in a fixed file directory. When visualizing, extract the environmental factor data in a continuous period from the fixed file directory; for the grid field data in the environmental factor data, use gradient colors to perform hierarchical visualization in chronological order, wherein the grid field data includes nitrogen concentration, phosphorus concentration, seawater temperature and seawater salinity; perform particle flow visualization on the ocean current field data; and superimpose the ocean current field data visualization layer on the grid field data visualization layer to realize the dynamic visualization of the nitrogen concentration, phosphorus concentration, seawater temperature and seawater salinity in the lagoon as the ocean current field changes.

[0039] In one embodiment, the data processing and visualization display process can be completed by the background program and the front-end program of the network service system, respectively. The background program periodically reads the 12-hour water environment spatial distribution field data of the island reef lagoon from a fixed file directory (centered on the data at the current moment, the data of the first 5 moments and the last 6 moments), and sends the water environment spatial distribution field data to the front-end program. After receiving the data, the front-end program uses gradient colors to perform hierarchical visualization of the raster field data such as seawater temperature, salinity, nitrogen concentration, phosphorus concentration, etc. in the lagoon in chronological order; and uses a particle flow visualization method for the vector data of the current field in the lagoon. The particle flow visualization of the current field is superimposed on the dynamic visualization layer of the raster field data to realize the dynamic visualization of the concentration of pollutants such as nitrogen and phosphorus in the lagoon as the current field changes.

[0040] As time goes by, the sensor acquires new real-time monitoring data and continuously repeats the S140 data prediction and dynamic display process, dynamically displaying on the front end the dynamic changes in the concentration of pollutants such as nitrogen and phosphorus in the lagoon as the ocean current field changes.

[0041] The remaining parts not described in detail belong to the common knowledge of those skilled in the art.

[0042] It is worth mentioning that the traditional physical dynamic mode technology mainly simulates and generates field data at different times based on historical observation data and field survey data, but this technology has disadvantages such as large amount of calculation, slow operation speed, and heavy reliance on supercomputers. When this technology is used alone for twin mapping of geographic processes, it cannot meet the real-time requirements. In order to make up for this defect, this embodiment introduces a deep learning model with extremely high computing efficiency into the twin mapping of geographic processes, inputs a large amount of time-series geographic process data into the deep learning model for training, obtains the evolution law of geographic processes from the data, and realizes the rapid simulation of geographic processes, thereby meeting the needs of real-time mapping of geographic processes. However, the deep learning model has high requirements for the quality and amount of training data. Generally, it is difficult to have high-precision observation data of a long time series for a geographic process in a small range of scenes. To this end, this embodiment integrates the physical dynamic mode with the deep learning model, relies on the physical dynamic mode to generate time-series high-precision geographic process simulation data, and provides it as a training data set to the deep learning model, which not only makes up for the data missing problem, but also can meet the needs of real-time mapping of geographic processes. In addition, since both the physical dynamic model and the deep learning model are simulations of geographic processes, in order to prevent error accumulation and ensure that the errors between the simulation results and the real scene data are within the allowable range, this embodiment deploys sensors for the target geographic process to obtain real-time monitoring data, and uses the real-time monitoring data to correct the above-mentioned model parameters to ensure that the simulation results are accurate and reliable, and ultimately meet the real-time and authenticity requirements of the twin mapping of the geographic process.

[0043] In summary, this embodiment provides a twin mapping method that integrates physical dynamic mode and deep learning model. It uses sensor real-time monitoring technology, combines traditional physical dynamic mode and lightweight deep learning model, and can quickly calculate the spatial distribution field data at different times in the future based on real-time monitoring data, so as to realize the twin mapping and visualization of the entire life cycle of the geodynamic process. The present invention overcomes the shortcomings of traditional high-precision hydrodynamic mode, such as large amount of calculation, slow calculation speed, and dependence on large supercomputers for computing power. It can quickly calculate the spatial distribution of pollutant concentration field and realize rapid twin mapping and visualization of geographic processes; while sensor monitoring data can only represent the "instantaneous" state of water environment elements at a certain monitoring point, and it is difficult to reflect the large-scale spatial distribution changes of geodynamic processes. The present invention can quickly calculate the spatial distribution field data of island, reef and lagoon water environment at different times in the future based on real-time monitoring data and using lightweight deep learning models.
